While running the delivery service, the couple started Campbell's Expedite Service in 1968. The second company focused on storage and delivery of oil.

About two years later, they bought property and started raising cattle as well.

Dennis Campbell recalled his mother telling him she was reluctant to live in the country.

“She was a city girl,” he said, “but she ended up loving to be in the country.”

Around 1983, Joyce Campbell and her husband sold the delivery service and ended Campbell's Expedite as well.

When not working, she enjoyed hunting, bowling, cooking and attending horse races. She was also a fan of the Spurs and the Dallas Cowboys.

Joyce Campbell and her husband worked together throughout their lives, which kept them very close, family said.

Her grandson, Aaron Ray Campbell, who was raised by her since he was 10 years old, also recalled his grandmother's devotion to family.

Aaron Campbell said growing up with his grandmother was fun, but she also taught him valuable lessons.

“She taught us ... how to be a gentleman, how to respect everyone you meet and how to keep in touch with people to network,” he said.

He recalled an instance years after moving out in which he was returning to his naval station in Hawaii after being deployed in the Arabian Gulf. Among the crowd of faces to greet the arrivals were his grandmother and his brother.

“I was proud that her and my brother had flown all the way out there to greet me,” Aaron Campbell said.
